When done right, acceptance criteria create a shared understanding across the team, defining exactly what each feature should achieve and how it will meet user needs.
When acceptance criteria are well-defined, they eliminate guesswork, minimize back-and-forth, and ensure that everyone has a unified understanding of what “done” truly means. But defining these criteria can be challenging, especially when juggling complex requirements and multiple stakeholders.

In this guide, we will walk you through how to create acceptance criteria that are practical, adaptable, and aligned with project goals. We’ll cover formats, templates, and tools that can streamline the process.
What are Acceptance Criteria?
Acceptance criteria are the exact conditions that define when a feature is “done” in agile development. But more than that, they’re an alignment tool that details what success looks like for a feature from both a user and business perspective.
Clear acceptance criteria translate a user story’s intent into specific, testable requirements, ensuring all stakeholders and team members share a single vision of “done.”
Importance and Role of Acceptance Criteria in Agile Development
When agile teams skip this step, they risk building features that technically work but miss the mark for the end-user. Acceptance criteria eliminate this risk by translating user stories into specific, testable requirements.
For example, say you’re developing a “password reset” feature. The user story might be, “As a user, I want to reset my password so I can regain access to my account.” This describes the need, but it doesn’t define the specifics.
Acceptance criteria bring this story to life by stating exactly what needs to happen, such as:
-The system sends a reset email within two minutes of the request.
-The reset link expires after 24 hours.
-If the email is invalid, the system provides an error message.
Without these details, different team members may interpret “password reset” differently, leading to a feature that doesn’t fully meet user or business expectations.
Types of Acceptance Criteria
Generally, acceptance criteria fall into two categories, functional and non-functional. Functional criteria focus on what the feature should do, while non-functional criteria address how well it performs.
Here’s a look at each type with a clear example to illustrate their roles.
Functional Acceptance Criteria
Functional acceptance criteria define specific actions or responses that a feature must support to meet user needs. They focus on direct functionality, answering the question, what should this feature accomplish?
For example, imagine a login feature for a mobile app. A functional criterion for this feature could be:
“The system should validate that the entered email and password match a registered account.”
This defines an essential functionality for the login feature, which is to confirm that only registered users can get access. It’s clear, testable, and leaves no ambiguity for the development team.
If the login system doesn’t correctly validate credentials, the feature doesn’t meet its core purpose.
Non-Functional Acceptance Criteria
Non-functional acceptance criteria set performance and quality standards for a feature. They address requirements like speed, reliability, and security, which might not be visible to the user but are essential for a seamless experience.
For example, for the same login feature, a non-functional criterion could be:
“The login page should load within 1 second on a standard network connection.”
This ensures that the login feature performs efficiently without any delays. A slow login page, even if functional, could frustrate users and discourage engagement.
So, by specifying a maximum load time, this non-functional criterion aligns the feature with user expectations for speed and responsiveness.
How to Write Effective Acceptance Criteria
Here’s how to write acceptance criteria that keep teams aligned and features on track.
Step-by-Step Guide to Writing Acceptance Criteria
Follow these steps to create criteria that are precise and actionable.
1. Anchor to the User Story’s Intent
Every acceptance criterion should directly support the purpose of the user story. So, always clarify the “why” behind the story.
For example, if the story is “As a user, I want to reset my password to regain access,” you’re addressing security, usability, and assurance.
So, your acceptance criteria might specify that a “password reset email is sent within 2 minutes,” signaling reliability and security.
2. Set Measurable Standards
Avoid vague terms like “quickly” or “intuitive.” Instead, define precise outcomes and replace “loads quickly” with “page loads within 2 seconds on a standard 4G network.”
It makes expectations clear and testing straightforward. Measurable standards also make it easy for QA to validate features consistently.
3. Use Simple, Direct Language
Acceptance criteria are for the whole team, including non-technical stakeholders. Everyone on the team, including non-technical stakeholders, should understand the expected outcome without guessing.
Instead of technical jargon, say, “System displays an error message for invalid passwords.” It is simple, and no one is left to interpret a vague term in multiple ways.
4. Employ the ‘Given-When-Then’ Format
A structured format like “Given-When-Then” offers clarity and consistency. It’s especially effective for behavior-driven development (BDD), which ensures the criteria align closely with user flows:
-Given a precondition (e.g., a user with a registered account)
-When an action occurs (e.g., they enter an incorrect password)
-Then the expected outcome follows (e.g., the system displays an error message)
This format breaks down the criteria into logical steps, making it easy for developers to implement and for QA to verify.
Common Mistakes to Avoid
Even with a structured approach, certain pitfalls can dilute the effectiveness of acceptance criteria. Here’s what to watch out for.
-Avoid subjective terms like “easy” or “fast” as they create ambiguity and misinterpretation.
-Focus on what needs to be achieved, not how it’s implemented.
-Failing to account for exceptions and error scenarios leads to incomplete functionality.
-Keep each criterion focused on a single outcome for clarity and testability.
Best Practices for Defining Clear and Concise Criteria
A disciplined approach to acceptance criteria can make a significant difference in development efficiency and also user satisfaction. You can follow these practices:
-Involve product owners, QA, and other stakeholders from the beginning. That way, everyone is aligned with business goals, user needs, and testing requirements, reducing the chance of revisions or misunderstandings.
-Avoid backend-oriented language and focus on the user experience. Instead of describing technical processes, write “User receives a confirmation email within 2 minutes after registration” to keep the team aligned with user expectations.
-Standards that are too ambitious can derail timelines and create bottlenecks. Review each criterion with the development team to confirm it’s achievable within the sprint and fits the project’s technical constraints.
-Regularly revisit criteria to ensure they align with any changes to the user story or project goals.
Acceptance Criteria Formats
Acceptance criteria are only as effective as their clarity. The format you use shapes how criteria are interpreted, implemented, and tested.
Here are three of the most effective formats:
Gherkin Syntax (Given-When-Then)
Gherkin syntax is structured and works especially well when you need to define a sequence of actions and results. If you’re working in Behavior-Driven Development (BDD), you’ve probably seen this format before. It sets up criteria like a story, so it’s easy for the team to follow each step.
Here’s how it works:
-Given establishes the starting conditions
-When describes the action taken by the user
-Then, outlines the outcome you expect
For example, let’s say you’re defining criteria for a password reset feature:
-Given a registered user
-When they request a password reset
-Then, the system sends a reset link to their email
Gherkin is perfect when you need criteria to flow in a step-by-step way, like features with specific sequences or dependencies.
Bullet Points and Checklists
Bullet points are straightforward and work best when your criteria are independent and don’t rely on a specific sequence. They let you list conditions one by one, making it easy for your team to see what needs to happen without unnecessary detail.
The structure is:
Each bullet or checklist item represents a single testable requirement.
For example, let’s consider a simple shopping cart:
-Cart updates total price when items are added or removed
-Success message appears when an item is added
-Users can change item quantities directly in the cart
Bullet points keep things simple. Each line is direct, so there’s no guesswork. It’s a format that’s easy to skim through and quick to validate, especially for features with clear, standalone requirements.
Scenario-based Criteria
Scenario-based criteria take a narrative approach, which is particularly useful if your feature has several paths a user might take. This format lets you lay out multiple scenarios within one feature so that you can cover edge cases and alternate paths more easily.
This is structured as follows:
Each scenario describes a specific interaction and expected outcome.
For a checkout process, your scenarios might look like this:
-Scenario 1: User with saved payment details completes checkout
-Scenario 2: User without saved details is prompted to enter payment information
-Scenario 3: Payment is declined, prompting the user to try another method
Scenario-based criteria capture different user flows and help teams prepare for edge cases. If your feature has multiple potential outcomes or complex logic, this format keeps everything organized and thorough.
Acceptance Criteria Templates
Templates provide a foundation for your criteria, but the key is adapting these templates to suit the specifics of your project, team dynamics, and user needs.
You can use free downloadable template here and Excel-based Acceptance Criteria Log template here. It is especially useful for tracking whether individual work items meet specified criteria, providing a clear, organized way to document testing outcomes.
Customizing Templates for Specific Projects
A pre-built template is only the starting point. To get real value, you need to adapt it to fit your project’s specific needs. Here’s how to customize acceptance criteria templates to make them work for your project.
-If your project has a security focus, make sure your criteria include specifics like encryption standards and multi-factor authentication.
-Select formats based on the demands of each feature. For multi-step workflows, a Given-When-Then structure is best. For simpler requirements, a checklist format keeps things efficient.
-As mentioned above, use plain language that captures the requirement without ambiguity.
-To make templates more actionable, add “Validation Steps” beneath each criterion.
-Modify the template to include edge cases and assumptions, especially for complex features.
